LIBRARY-SHELVING.

SPECIFICATION forming part of Letters Patent N o. 618,511, dated January 31, 1899. Application filed November 26 1897. Serial No. 659,825. (No model.)

To ctZZ whom t may concern,.-

Be it known that I, JACKSON L. KAIL, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Library-Shelving, of which the following is a specification.

My invention relates to certain new and useful improvements in library-shelving, the object being to produce a shelving in which the supporting members shall be of neat and simple construction and the brackets easily applied or removed therefrom.

It also relates to certain novel features of construction, a description of which will be found in the following specification, and the essential features more definitely pointed out in the claims appended thereto.

The invention is illustrated in the drawings accompanying the specification by means of iive figures, of which- Figure l is a side elevation of a portion of an upright and bracket clamped thereto, showing a shelf in transverse section supported upon the bracket and partly broken away. Fig. 2 is a view, partly in horizontal section and partly in top plan, of the upright and bracket, the line of section being indicated at 2 2 in Fig. l. Fig. 3 is a perspective View of the forward edge of the bracket with a shelf supported thereon. Fig. 4 is a front View of two adjacent brackets and shelves; and Fig. 5 is a detail horizontal section in line 5 5 of Fig. l, the View being upon an enlarged scale.

In the views, Arepresents an upright, and.

B a bracket, containing my improvements. As shown, the upright consists of a thin bar d, to which are secured clamping-bars d in such a manner as to leave a slight space between the two, the object of which will appear below. The means employed for spacing these bars apart is not material; but the one which I have shown is preferred, it being the cheapest, neatest, and simplest way of doing the same. As seenin Figs. l and 5, I form bosses a2 in the bars a at suitable 'intervals by stamping the metal inward and punching holes in theV bosses. The clamping-bars are then secured to the main bar a by riveting them together, the heads of the rivets being seated in the depressions left above the bosses,and therefore out of the way, so that the bracket may be adjusted up and down upon the clamping-bar without being interfered with by said rivets.

The bracket may be of any'ornamental design suitable for the purpose. I have found that the forward edge of the bracket is apt to spring away from the shelf, thereby leaving a slight space between the edge of the shelf and the bracket, so that the cover of the book adjacent to the bracket will slip down'into the space. To obviate this diflculty, I form a recess b in the face of the bracket adjacent to the shelf, into which the end of the latter extends, lugs b' being formed upon the bracket immediately below the shelf and adapted to form a support therefor. On the forward edge of the shelf, which is lettered C, is secured a clip c, bent at right angles to itself to form a hook adapted to engage the bracket and prevent it from swinging away from the shelf. A hole c2 is made in the clip, through which a screw-driver may be inserted in adjusting the shelf upon the standard.

Upon the edge of the bracket adjacent to the standard are formed two lugs b2 b2, (see Figs. 1, 2, and 5,) said lugs being adapted to hold the bracket in line with the clampingbar, and on the opposite face of the bracket is formed another lug b3, formed with an opening b, in which is seated a screw E, threaded in a clamping-block D and adapted by its rotation to move the same into or out of engagement with the clamping-bar a. The clamping-block is formed with a guiding-lug d, eX- tending along one face of the lug b3 and adapted to prevent rotation of the clamping-block D with reference to the bracket when not in engagement with the clamping-bar. The

block is also formed with a hook d', extending around the edge of the clamping-bar and is adapted to grasp the same when the screw E is rotated in the proper direction. rlhis block is preferably constructed of some noncorrosive metal-as, forinstance, bronze-the obj ect being to prevent the screw from becom ing fastened therein after a length of time. A ring e is forced into the opening b4 after the screw has been inserted therein, so that in IOO nnscrewin g the screw the block will be forced away from the clamping-bar instead of the screw being forced out of the opening h4.

I am aware that various alterations and modiiications of this device are possible, and I do not therefore desire to limit myself to the exact construction thereof; but what I do believe to be 'new and essential to the embodiment of my invention will be found in the following claims.

I claim as new and desire to secure by Letters Patentl. The combination with a suitable support ofa bracket adjustably secured thereto by means of a clamping-screw, a shelf supported upon the bracket, and a clip, c, secured to the shelf and engaging the bracket upon the opposite side of the shelf end, said clip beings,`
